摘要： A light source device (100) is provided with a light source lamp unit (1) which is detachably attached to the device (100) and a CPU (101) which constitutes the drive control means of the lamp unit. The CPU (101) detects the information about the electric power and service life of a lamp and whether the lamp is new or old carried by the lamp information carrying section (5) of the unit (1) and, when the lamp is turned on, counts the cumulative operating hour of the lamp. The CPU (101) compares the detected service life with the cumulative operating hour and, when the service life has expired, forcibly turns off the lamp. The CPU (101) also warns the user of the necessity of replacing the lamp by displaying a warning a fixed period of time short of the expiration of the service life. Since the information about the kind and characteristics of the lamp is carried by the lamp information carrying section (5) of the unit (1), the light source device (100) can appropriately discriminate and control the turning on/off and service life of a lamp even when a different kind of light source lamp unit is used.

摘要： A projection type display device which prevents light from a dichroic prism (910) constituting color synthesis means of an optical system, etc., from entering the back side of a liquid crystal light valve. The dichroic prism (910) comprises four triangular prisms having an equal refractive index, and a glass filter (912) for absorbing and cutting off a blue luminous flux is bonded to the incidence surface (910R) of a red luminous flux. After passing through each light valve (925), a modulated luminous flux of each color passes through a prism unit, is reflected by its X-shaped reflection surface and is directed toward the projection lens unit 6. At this time, part of the blue luminous flux may not be reflected by the reflection surface but incident on the back of the red light valve (925R). Light leaking from the prism in this way is absorbed and cut off by the filter (912). Accordingly, it is possible to prevent the erroneous operation of the liquid crystal light valve due to the entrance of light from the back surface.
摘要翻译：一种防止来自构成光学系统的颜色合成装置等的二向色棱镜（910）的光进入液晶光阀背面的投射型显示装置。二向色棱镜（910）包括具有相同折射率的四个三棱镜，并且用于吸收和切断蓝色光束的玻璃滤光器（912）被结合到红色光通量的入射表面（910R）。在通过每个光阀（925）之后，每种颜色的调制光通量通过棱镜单元，被其X形反射面反射并被指向投影透镜单元6.此时，部分蓝色光通量可能不被反射表面反射，而是入射到红光阀（925R）的背面。以这种方式从棱镜泄漏的光被过滤器（912）吸收并切断。因此，可以防止由于来自背面的光的入射引起的液晶光阀的错误操作。
